[0070] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present application and do not limit the present application.

[0071] In the related art, most of the vehicle door opening methods use side-opening doors. In an environment where more and more users pursue personalization and fashion, more personalized door opening methods are needed, so it is necessary to develop personalized and fashionable door opening methods to meet market demand. As a special door opening method, the swing door is not only novel and fashionable in opening, which can cater to the personalized needs of consumers, but also can meet the needs of consumers for the convenience of getting on and off the vehicle with a smaller door opening width, solving the problem of inconvenience for passengers getting on and off the vehicle when the parking space is narrow. However, there are very few hinge structures similar to the door opening method on the market, which are mainly used in high-end sports cars, but their structure is relatively complex, with high precision requirements, and there are defects such as high cost and complex assembly, which do not meet the needs of generalization and mass production.

[0072] See also Figure 1 The present application provides a vehicle door hinge and a vehicle, wherein the vehicle door hinge 3 is used to be installed between a vehicle body 2 and a vehicle door 1 to realize that the vehicle door 1 is pivotally connected to the vehicle body 2 .

[0073] The following will refer to Figures 1 to 6 The vehicle door hinge 3 according to the present application will be described in detail.

[0074] The door hinge may include a first drive member 360, a first mounting bracket 310, a transmission member 340 and a second mounting bracket. The first mounting bracket 310 is suitable for being fixedly connected to the door. The first mounting bracket 310 is connected to the first drive member 360, for example, the first mounting bracket 310 is fixedly connected to the first drive member 360. The transmission member 340 is in transmission connection with the first drive member 360. And the transmission member 340 is connected to the first mounting bracket 310, for example, the transmission member 340 may be rotatably connected to the first mounting bracket 310 around its own axis. The second mounting bracket is suitable for being fixedly connected to the vehicle. And the second mounting bracket is suitable for cooperating with the transmission member 340, so that when the first driving member 360 drives the transmission member 340 to perform rotational motion, the first mounting bracket 310 can perform linear motion away from the second mounting bracket along the axis direction of the transmission member 340.

[0075] According to the door hinge of the first aspect of the present application, the first driving member 360 can drive the transmission member 340 to rotate around the axis of the transmission member 340, thereby driving the first mounting bracket 310 to move linearly away from the second mounting bracket along the axis direction of the transmission member 340, and then driving the door to move linearly away from the vehicle body along the axis direction of the transmission member 340 relative to the vehicle body when the door hinge is installed to the vehicle. Compared with the prior art, the structure of the door hinge of the present application is simpler and more compact, which helps to reduce costs and facilitates promotion and application; at the same time, it is more stable, reliable and convenient in realizing the functions of opening and closing the door; further, since the first driving member 360 will be installed to the door in the installed state, it is conducive to ensuring that the side wall of the vehicle body has a more flexible installation space, and can also ensure that the side wall of the vehicle body has a higher strength. Furthermore, the door hinge of the present application can meet the personalized needs of users for the vehicle door opening method, and can allow the door to meet the convenience needs of users in getting on and off the vehicle with a smaller door opening width, solving the problem of inconvenience for users to get on and off the vehicle when the parking space is narrow.

[0076] Further, the transmission member 340 passes through the through hole and is connected with the second mounting bracket 350. The transmission member 340 can be connected with the second mounting bracket 350 by a ball screw. Alternatively, the transmission member 340 can also be connected with the second mounting bracket 350 by a screw nut.

[0077] For example, the transmission member 340 is configured as a first screw rod. The second mounting bracket 350 is provided with a through hole (not marked). The first screw rod passes through the through hole and is threadedly engaged with the second mounting bracket 350. Here, the through hole can be configured as a threaded hole that is threadedly engaged with the first screw rod. A nut can also be added at a position corresponding to the position of the through hole, and the nut is threadedly engaged with the first screw rod. Further, the nut here can be located outside the through hole or embedded in the through hole. The first screw rod is used to be rotatably arranged relative to the second mounting bracket 350 around the axis of the transmission member 340. In the installation state where the door hinge of the present application is installed to the vehicle, the first screw rod is rotatably connected to the vehicle door 1 around the axis of the transmission member 340. The axis of the first screw rod is the own axis of the above-mentioned transmission member 340. The first screw rod here can be the above-mentioned transmission member 340, or it can be a part of the above-mentioned transmission member 340.

[0078] In addition, the door hinge 3 according to the present application may further include a switching device 330. The switching device 330 is connected between the first screw rod 340 and the second mounting bracket 350. The switching device 330 is arranged on one of the second mounting bracket 350 and the transmission member 340. The switching device 330 is suitable for being connected with the other of the second mounting bracket 350 and the transmission member 340 so that the second mounting bracket 350 switches from linear motion to rotational motion. The switching device 330 has an engaged state and a disengaged state. The first driving member 360 has an output shaft. The output shaft is transmission-connected to the first screw rod 340. And the axis of the output shaft does not coincide with the axis of the transmission member. The door hinge 3 here is constructed so that:

[0079] When the switching device 330 is in an engaged state, the first driving member 360 can drive the door 1 to rotate around the axis of the transmission member. When the switching device 330 is in a disengaged state, the first driving member 360 can drive the door 1 to move relative to the vehicle body 2 in a direction parallel to the axis of the transmission member.

[0080] For example, a connecting portion 340a is provided on the transmission member 340. The connecting portion 340a is provided on a side of the second mounting bracket 350 away from the first mounting bracket 310. The switching device 330 is provided on a side of the second mounting bracket 350 facing the connecting portion 340a. The connecting portion 340a is suitable for connecting to the switching device 330. The transmission member 340 here can be configured as a first screw rod. The connecting portion 340a can be the outer peripheral surface of the first screw rod, for example, an external threaded portion.

[0081] According to the vehicle door hinge 3 of the present application, the movement relationship between the first screw rod 340 and the second mounting bracket 350 can be adjusted by setting the switching device 330, and the vehicle door 1 can be driven to move relative to the vehicle body 2 when the vehicle door hinge 3 is in the installed state by setting the first driving member 360. Compared with the prior art, the structure of the vehicle door hinge 3 of the present application is simpler and more compact, which helps to reduce costs and is convenient for promotion and application; at the same time, it is more stable, reliable and convenient in realizing the functions of opening and closing the vehicle door 1; further, since the first driving member 360 will be installed to the vehicle door 1 in the installed state, it is conducive to ensuring that the side wall of the vehicle body 2 has a more flexible installation space. Furthermore, the vehicle door hinge 3 of the present application can meet the personalized needs of users for the opening method of the vehicle door 1 of the corresponding vehicle, and the vehicle door 1 can meet the convenience needs of users in getting on and off the vehicle with a smaller door opening width, solving the problem of inconvenience for users to get on and off the vehicle when the parking space is narrow.

[0082] For example, the switching device 330 is disposed on the second mounting bracket 350. And the switching device 330 can be configured as a clutch device or a brake.

[0083] In addition, the door hinge 3 may further include a first speed change assembly. The first drive member 360 is transmission-connected to the first mounting bracket 310 via the first speed change assembly. The first speed change assembly is rotatably connected to the first mounting bracket 310. The first speed change assembly is used to be mounted to the door 1. The output shaft is transmission-connected to the first screw rod 340 via the first speed change assembly. That is, the first drive member 360 is transmission-connected to the first screw rod 340 via the first speed change assembly.

[0084] See also Figures 1 to 3 In one example of the present application, the first drive member 360 may be configured as a motor. The axis of the output shaft of the motor is parallel to the axis of the first screw rod 340. The axis of the output shaft is coplanar with the axis of the first screw rod 340. The first speed change assembly may include a first gear 370 and a second gear 320. The first gear 370 is coaxially arranged with the output shaft. And the first gear 370 is fixed relative to the output shaft. The second gear 320 is coaxially arranged with the first screw rod 340. And the second gear 320 is fixed relative to the first screw rod 340. The second gear 320 is meshed with the first gear 370. When the first drive member 360 is turned on, the first gear 370 can be driven to rotate, thereby driving the second gear 320 to rotate. When the rotation of the first screw rod 340 is blocked, the first gear 370 rotates around the second gear 320, thereby driving the first drive member 360 to rotate around the axis of the transmission member.

[0085] For example, the axis of the output shaft is parallel to the axis of the transmission member. The first gear 370 and the second gear 320 here can be spur gears.

[0086] For another example, the axis of the output shaft may also be perpendicular to the axis of the transmission member. The first gear 370 and the second gear 320 here may be configured as bevel gears.

[0087] See also Figure 4 In another example of the present application, the first drive member 360 can be configured as a motor. The axis of the output shaft of the motor is parallel to the axis of the first screw 340. The axis of the output shaft is coplanar with the axis of the first screw 340. The axis of the output shaft is skewed with the axis of the transmission member. The first speed change assembly may include a worm wheel 620 and a worm 610 that mesh with each other. One of the worm wheel 620 and the worm 610 is coaxially arranged with the output shaft and fixed relative to the output shaft. The other of the worm wheel 620 and the worm 610 is coaxially arranged with the first screw 340 axis and fixed relative to the first screw 340. In the illustrated example, the worm wheel 620 is connected to the first screw 340. The axis of the worm wheel 620 is perpendicular to the axis of the worm 610.

[0088] In any of the above examples, the transmission ratio of the first speed change assembly is greater than 1. This can increase the torque of the first screw rod 340 .

[0089] For example, the first mounting bracket 310 is used to be mounted to the vehicle door 1. The second mounting bracket 350 is used to be mounted to the vehicle body 2. The first screw rod 340 is rotatably connected to the first mounting bracket 310. The nut is fixedly arranged relative to the second mounting bracket 350. The nut is connected to the second mounting bracket 350, or the nut and the second mounting bracket 350 are constructed as one body.

[0090] In addition, the door hinge 3 may further include a first bearing 390 and a second bearing 380. The first bearing 390 is sleeved on the outer side of the first screw rod 340 and connected to the first mounting bracket 310 to allow the first screw rod 340 to rotate relative to the first mounting bracket 310. The output shaft may be connected to the second mounting bracket 350 through the second bearing 380 to allow the output shaft to rotate relative to the second mounting bracket 350.

[0091] In other examples of the present application, the output shaft can be connected to a transmission shaft. The transmission shaft is connected to the second mounting bracket 350 through a second bearing 380. The transmission shaft can be used to mount a part of the first transmission assembly, such as the first gear 370.

[0092] For example, the first mounting bracket 310 includes two plates connected to each other. A receiving space is formed between the two plates. The transmission member 340 is respectively connected to the two plates through the first bearing 390. The first speed change assembly can be arranged in the receiving space.

[0093] For example, the switching device 330 is configured as a switching device 330 that can be controlled to switch between an engaged state and a disengaged state. The door hinge 3 may also include a first angle detection device (not shown), a second angle detection device (not shown) and a control device (not shown). The first angle detection device is mounted to the first drive member 360, and is used to detect a first angle of rotation of the output shaft along a first rotation direction. The second angle detection device is mounted to the first drive member 360, and is used to detect a second angle of rotation of the output shaft along a second rotation direction. The second rotation direction is opposite to the first rotation direction. The control device is respectively connected to the first angle detection device, the second angle detection device and the switching device 330. The control device is configured to be able to perform the following steps:

[0094] The output shaft of the first driving member 360 is controlled to rotate in the first rotation direction, the first angle of the first angle detection device is received during the rotation of the output shaft in the first rotation direction, and the switching device 330 is controlled to switch to the engaged state when the first angle reaches the first preset switching angle, and the output shaft is controlled to stop rotating when the first angle reaches the first preset termination angle. The angle difference between the first preset switching angle and the first preset termination angle can be in the range of 85° to 95°.

[0095] Control the output shaft of the first driving member 360 to rotate along the second rotation direction, receive the second angle of the second angle detection device during the rotation of the output shaft along the second rotation direction, and control the switching device 330 to switch to a disengaged state when the second angle reaches a second preset switching angle, and control the output shaft to stop rotating when the second angle reaches a second preset termination angle.

[0096] Optionally, the first angle detection device and the second angle detection device may be configured as Hall sensors.

[0097] For example, the switching device is a clutch device. The clutch device may include a housing 331, a first friction plate and a second friction plate arranged opposite to each other, an elastic member 334, and a pull rod 333. The housing 331 is connected to the second mounting bracket. The first end of the first friction plate is rotatably connected to the first end of the second friction plate. And the first end of the first friction plate and the first end of the second friction plate are both rotatably connected to the housing 331. The first friction plate and the second friction plate are suitable for being connected to the connecting portion 340a. The elastic member 334 is arranged between the second end of the first friction plate and the second end of the second friction plate, so that the second end of the first friction plate and the second end of the second friction plate are arranged at intervals under the action of elastic force. The pull rod 333 is connected to the second end of the first friction plate and the second end of the second friction plate. The pull rod 333 is suitable for being connected to the second driving member 336, so that the second end of the first friction plate and the second end of the second friction plate overcome the elastic force of the elastic member 334 under the action of the second driving member 336 to approach each other, thereby connecting the first friction plate and the second friction plate to the connecting portion 340a.

[0098] See also Figure 5, the switching device 330 may include a housing 331, a friction plate 332, a pull rod 333, an elastic member 334 and a second driving member 336. The housing 331 is constructed as an annular member. The housing 331 has a positioning protrusion 331b protruding radially outward. The positioning protrusion 331b here is used to position and cooperate with the positioning notch on the second mounting bracket 350. The positioning protrusion 331b is provided with a mounting hole 331a, which is used to penetrate a screw to fasten the housing 331 to the second mounting bracket 350. Two friction plates 332 are provided. The friction plates 332 are semicircular. The two friction plates 332 are arranged oppositely and the concave surfaces face each other. The same end of the two friction plates 332 is pivotally connected to the housing 331 through a pivot 335, and the same other end of the two friction plates 332 is respectively configured with a connecting ear 332a. The pull rod 333 passes through the two connecting ears 332a and is connected to the second driving member 336. A limit portion 333a is provided at one end of the pull rod 333 away from the second driving member 336, and the limit portion 333a is used to prevent the pull rod 333 from being separated from the friction plate 332. An elastic member 334 is also installed between the two connecting ears 332a. The elastic member 334 is used to apply a force to the two friction plates 332 to make the two connecting ears 332a move away from each other. The second driving member 336 can be configured as an electric cylinder. The telescopic rod of the electric cylinder is connected to the pull rod 333 to drive the pull rod 333 to pull one of the two connecting ears 332a away from the electric cylinder, so that the two connecting ears 332a are close to each other, thereby switching the switching device 330 to the engaged state. When the telescopic rod of the electric cylinder is extended or the power is cut off, the two connecting ears 332a are reset under the action of the elastic member 334, so that the switching device 330 is switched to the separated state. Among them, the elastic member 334 can be configured as a spring.

[0099] Optionally, a through hole corresponding to the through hole is provided on the housing 331. The transmission member 340 passes through the through hole. The first friction plate and the second friction plate are both arc-shaped structures adapted to the through hole.

[0100] Figure 1 The figure is a schematic diagram of the installation of the door hinge 3. One end of the door hinge 3 is installed on the door 1, which is the driving end of the hinge. The hinge mechanism mounting bracket installed on the door 1 is hidden between the inner and outer panels of the door, and the driving motor is placed in the inner door guard plate 4, which can ensure the aesthetic appearance of the vehicle. The other end of the hinge mechanism is installed on the side panel assembly, mainly to constrain the verticality of the hinge rotation axis. The guide pin is installed on the side panel assembly and cooperates with the door 1. The guide pin is designed as a telescopic movement mechanism. When the door 1 moves laterally, the guide pin moves with the door 1 to guide and stabilize. When it is detected that the door 1 is about to rotate, the guide pin immediately retracts into the side panel assembly, as shown in the dotted line state in the figure, which can ensure a neat appearance and avoid interference with the door 1 during the rotation.

[0101] Figure 2The schematic diagram of the structure of a door hinge 3 of an example of the present application. The door hinge 3 includes a first mounting bracket 310, a second gear 320, a switching device 330, a first screw rod 340, a second mounting bracket 350, a first driving member 360, a first gear 370, a first bearing 390 and a second bearing 380. The first driving member 360 is hidden between the guard plate 4 and the inner door panel. The first driving member 360 is fixedly connected to the first gear 370. The first gear 370 is connected to the first mounting bracket 310 through the second bearing 380. The first gear 370 and the second gear 320 are driven by gear meshing. The second gear 320 and the first screw rod 340 are fixedly connected by splines. The first screw rod 340 is connected to the first mounting bracket 310 through the first bearing 390. The first mounting bracket 310 is fixed to the inner door panel and hidden between the inner door panel and the outer door of the vehicle door. The first screw rod 340 is threadably matched with the second mounting bracket 350 to convert the rotational movement of the first screw rod 340 into the lateral movement of the vehicle door 1. The second mounting bracket 350 is equipped with a switching device 330. When the end of the first screw rod 340 moves into the second mounting bracket 350, the state of the switching device 330 is switched to a combined state to fix the second mounting bracket 350 with the first screw rod 340. Since the second mounting bracket 350 is fixed to the side assembly of the vehicle body 2, the first screw rod 340 stops rotating. At this time, the vehicle door 1 rotates around the first screw rod 340 under the drive of the first driving member 360 to realize the rotational movement of the vehicle door. The first driving member 360 here is, for example, a driving motor.

[0102] When the door opening signal is transmitted to the drive motor through the wiring harness, the rotation of the drive motor drives the first gear 370 that moves coaxially to rotate forward, thereby driving the second gear 320 to rotate, and then the second gear 320 drives the first screw rod 340 to rotate integrally. Due to the limiting effect of the guide pin as the guide assembly 5, the door 1 can only move outward in the lateral direction, that is, in the width direction of the vehicle. With the rotation of the first screw rod 340, the door 1 and the first mounting bracket 310, the drive motor, the first gear 370, and the second gear 320 all move laterally. During the lateral movement, the lateral movement distance is detected or the rotation angle of the output shaft is detected. After reaching a certain value, the switching device 330 switches to the engagement state to fix the second mounting bracket 350 with the first screw rod 340. The second gear 320 is fixed when the first screw rod 340 stops moving. Driven by the drive motor, the door 1 and the first mounting bracket 310 rotate around the second gear 320 together with the first gear 370, so that the door 1 rotates and opens, and finally the swing door is opened.

[0103] When the door closing signal is transmitted to the drive motor through the wiring harness, the door 1 is reversed to a horizontal position by the rotation of the drive motor. At this time, the guide pin is extended, and the switching device 330 disconnects the fixed connection between the second mounting bracket 350 and the first screw rod 340. The door 1 moves laterally with the rotation of the first screw rod 340, thereby completing the closing of the swing door.

[0104] See also Figures 1 to 5 The present application also provides a control method for a vehicle door hinge. The control method can be used for the above-mentioned vehicle door hinge 3. The control method can include a door opening control method and a door closing control method.

[0105] The door opening control method may include the following steps:

[0106] In response to the door opening request signal, a door opening start signal is sent to the first driving member 360 to control the output shaft of the first driving member 360 to rotate along the first rotation direction;

[0107] During the process of the output shaft rotating along the first rotation direction, the first angle detected by the first angle detection device is received, and when the first angle reaches the first preset switching angle, an engagement control signal is sent to the switching device 330 to control the switching device 330 to switch to the engagement state, and when the first angle reaches the first preset end angle, a door opening stop signal is sent to the first driving member 360 to control the output shaft to stop rotating.

[0108] The door closing control method may include the following steps:

[0109] In response to the door closing request signal, sending a door closing start signal to the first driving member 360 to control the output shaft of the first driving member 360 to rotate along the second rotation direction;

[0110] During the process of the output shaft rotating along the second rotation direction, the second angle detected by the second angle detection device is received, and when the second angle reaches the second preset switching angle, a separation control signal is sent to the switching device 330 to control the switching device 330 to switch to the separation state, and when the second angle reaches the second preset end angle, a door closing stop signal is sent to the first drive member 360 to control the output shaft to stop rotating.

[0111] According to the control method of the vehicle door hinge of the present application, when applied to the above-mentioned vehicle door hinge 3, the vehicle door 1 can be opened and closed automatically, and the operation is convenient. At the same time, the vehicle door 1 has translation and rotation movements during the opening and closing process, which helps to improve the user experience.

[0112] See also Figures 1 to 6The present application also provides a vehicle. The vehicle may include a vehicle body 2, a vehicle door 1 and the above-mentioned vehicle door hinge 3.

The first transmission assembly and the first drive member 360 are located in the accommodating cavity. The above-mentioned first mounting bracket 310 is fixed to the inner panel and is located in the first cavity. The above-mentioned first drive member 360 is fixed to the inner panel and is located in the second cavity. The vehicle door hinge 3 is connected to the A-pillar and the vehicle door 1. When the vehicle door 1 is rotated to open, the vehicle door 1 uses the connection between the vehicle door hinge 3 and the A-pillar as a supporting structure and flips forward to open the vehicle door.

[0113] According to the vehicle of the present application, by applying the above-mentioned door hinge 3, the door 1 can meet the personalized needs of the user for the opening method of the door 1 of the corresponding vehicle, and the door 1 can meet the convenience needs of the user in getting on and off the vehicle with a smaller door opening width, solving the problem of inconvenience for users to get on and off the vehicle when the parking space is narrow. Moreover, the structure of the door hinge 3 of the present application is simpler and more compact, which helps to reduce costs and facilitates promotion and application; at the same time, it is more stable, reliable and convenient in realizing the functions of opening and closing the door 1; further, since the first drive member 360 will be installed to the door 1 in the installed state, it is conducive to ensuring that the side of the vehicle body 2 has a more ample installation space.

[0114] In an example not shown in the present application, the door hinge 3 may also be arranged at other positions such as the B-pillar.

[0115] See also Figure 1 and Figure 6 In addition, the vehicle may further include a guide assembly 5. The guide assembly 5 is movably connected to the vehicle body 2 between an extended position and a retracted position in a direction parallel to the axis of the transmission member. The vehicle door 1 has a guide hole. The vehicle door hinge 3 is constructed so that: when the switching device 330 is in a disengaged state, the guide assembly 5 is in an extended position, and the guide hole is slidably fitted to the guide hole in a direction parallel to the axis of the transmission member, and the first drive member 360 drives the vehicle door 1 to move relative to the vehicle body 2 in a direction parallel to the axis of the transmission member. When the switching device 330 is in an engaged state, the guide assembly 5 is in a retracted position and disengaged from the guide hole, and the first drive member 360 drives the vehicle door 1 to rotate around the axis of the transmission member. By setting the guide assembly 5, the movement relationship of the vehicle door 1 relative to the vehicle body 2 can be adjusted when the vehicle door hinge 3 is in an installed state.

[0116] Further, the vehicle may also include a third driving member. The guide assembly 5 may include a guide pin.

And the second screw rod 510 is matched and connected with the nut 520. Among them, the nut 520 is slidably arranged relative to the vehicle body along the axis direction of the transmission member, i.e., the first screw rod. The second screw rod 510 is parallel or substantially parallel to the first screw rod. Substantially parallel here can be understood as that the axis of the first screw rod and the axis of the second screw rod 510 are allowed to have a certain assembly error, and within the range of the assembly error allowed, the axis of the first screw rod and the axis of the second screw rod 510 may not be parallel and have a small angle, for example, the angle is within 5°. The third drive member 500 here can be a motor. The second speed change assembly 530 may be configured as a gear assembly, and the gear assembly may include two or more gears meshingly connected to each other.

[0118] Optionally, the guide assembly 5 may further include a housing. The housing is used to mount the guide pin 540, the third driving member 500, the second screw rod 510 and the nut 520. In this way, the guide assembly 5 can be produced and sold as a separate product or intermediate product, or as a spare part for maintenance. During the production process, the guide assembly 5 can be produced separately and then assembled with the vehicle body and the door, which helps to improve production efficiency and product quality.

[0119] In another example, the third driving member and the guide assembly 5 are two independent parts. The third driving member is connected to the guide assembly 5. The guide assembly 5 here is configured as a guide pin. By starting the third driving member, the guide assembly 5 can be driven to extend and retract. The third driving member here can be configured as an electric cylinder. The telescopic rod of the electric cylinder is connected to the guide pin. By starting the electric cylinder, the guide pin can be driven to perform telescopic movement.

[0120] In other examples, the electric cylinder may also be replaced by an electric push rod.
